Jack Posted October 8, 2017 Share Posted October 8, 2017 Hello all, I have a [url="http://www.drbasscabs.com/products.html"]Dr. Bass 2460[/url] that I'm keen to restore. The first thing that I need to do is replace the chipped and battered metal corners. I'd quite like something chunkier and heavy duty like I had on my older GK cabs. The current ones look like the barefaced ones, [url="https://www.thomann.de/gb/adam_hall_4023_radiusecke.htm"]kind of like these[/url]. I want something [url="https://www.thomann.de/gb/adam_hall_4013_ecke.htm"]more like these[/url]. The problem I have the this 'inner radius' malarkey. Firstly, specifically, optimistically, what's the correct radius to buy for my Dr. Bass cabinet? Secondly, and perhaps more realistically, how do I measure and determine this for myself? I assume I can take a ruler or something to either the old corner protector or the cab itself? Thanks! Quote Link to comment Share on other sites More sharing options...
Matt P Posted October 8, 2017 Share Posted October 8, 2017 i would make a gauge, get a bit of stiff cardboard and a pair of compasses, draw in the 10mm radius on the card and cut it out with a sharp craft knife, then compare it to the radius on the cab, you want the same radius or smaller for the new corners or you'll need to sand the edges to suit the new corners. this is what set of radius gauges looks like, not difficult to make a few in cardboard to see what you've got. https://en.wikipedia.org/wiki/Radius_gauge#/media/File:RadiusGauges2.jpg Matt Quote Link to comment Share on other sites More sharing options...
Bill Fitzmaurice Posted October 8, 2017 Share Posted October 8, 2017 The standard corner radius in the US is 3/8 inch. You don't need a gauge to measure it, just a ruler and a straight edge. Place the straight edge on one surface, extending beyond the joint of the two panels, use the ruler placed on the intersecting surface to measure the distance from where the chamfer begins to the straight edge.

Jack Posted October 12, 2017 Author Share Posted October 12, 2017 Thanks, gents. Next time I'm at my locker I'll remove a corner and try exactly this. Quote Link to comment Share on other sites More sharing options...
Alec Posted October 18, 2017 Share Posted October 18, 2017 (edited) [quote name='Bill Fitzmaurice' timestamp='1507474193' post='3385692'] The standard corner radius in the US is 3/8 inch. [/quote] Which, when converted from US antiquity to International standard units, is 9.525 mm, so pretty close to 10mm Edited October 18, 2017 by Alec Quote Link to comment Share on other sites More sharing options...
Bill Fitzmaurice Posted October 18, 2017 Share Posted October 18, 2017 After all the toil and trouble you Brits went through to defeat Napoleon you go and adopt his system of weights and measures, and relegate good King Henry VII to the dust bin. What's next for you? Drinking cold beer? Quote Link to comment Share on other sites More sharing options...
